STAND-PIPE FOR SUPPLYING WATER TO LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 426,124, dated April 22, 1890.

Application filed November 29, 1889. Serial No. 331,838. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. JAcKsoN, a citizen of the United States, residing at Three Rivers, in the county of St. Joseph and State of Michigan, have invented a new and useful Stand-Pipe for Supplying ater to Locomotives, of which the following is a specification.

This invention relates to stand-pipes for supplying water to locomotives and for other purposes; and it has for its object to provide a device which shall be simple, durable, and efficient in operation.

The invention consists- First, in constructing the stand-pipe with a flexible joint, whereby normally it. shall occupy a straight vertical position. hen it is desired to top the pipe, the upper portion, having the spout or nozzle, may be lowered to a horizontal position.

Secondly, in an improved construction of the valve, which is provided with mechanism for relieving it from excessive water-pressure, thereby enabling it to turn smoothly and freely.

Thirdly, in the arrangement of a reliefvalve for protecting the pipe from the inj urious effects of the water-hammer when the valve is closed.

The invention further and finally consists in the improved construction and arrangement of details, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a front view showing the stand-pipe in a raised position. Fig. 2 is a perspective view showing the stand-pipe with its upper end lowered and in position for being tapped. Fig. 3 is a side view with dotted lines showing the upper end 01 the stand-pipe lowered. Fig. 4 is a front view of the lower end of the stand-pipe and the valve-casing. Fig. 5 is a vertical sectional view of the main valve and valve casing. Fi 6 and '7 are detail views of the main valve. Fig.8 is a detail side view of the lower end of the standpipe. Fig. 9 is a detail view of the cylinder and piston to relieve pressure upon the main valve.

Like numerals of reference indicate like parts in all the figures.

.1. designates an elbow, which constitutes the valve-casing, and which is provided with a base 2. wardly from the elbow, comprises the lower rigid portion 3 and the upper rigid. portion or drop-pipe 4, which is provided wit-h a union or swiveled elbow 5, forming a discharge-11ozzle. A fiexiblepipe 6, of suitable construction, connects the portions and a of the standpipe. To the drop-pipe & is pivoted a handlever 7, for operating the valve.

The upper end of the lower portion 3 of the stand-pipe is provided with a pair of upwardly-extending rigid arms 8 S, to the upper ends of which are fulcrumed a pair of rigid arms or levers S) 9, extending downwardly from the drop-pipe at. The lower ends of the levers 9 9 are connected by rods 10 10 with an annular weight 11, encircling the stand-pipe and serving to hold the drop-pipe normally in a raised or vertical position. The fulcrum of the levers 9 being near the middle of the flexible pipe (3, the drop-pipe may readily be lowered to the approximately horizontal position shown in Fig. 2 and in dotted. lines in Fig. 3 of the drawings.

The elbow or valve-easing 1 contains the valve,which consists of the conical or frustumshaped members 12 and 13, the former of which forms a seat for the latter. The conical outer member 12 has at its front end a tubular stem 14, which projects through an opening 15, formed in the elbow or casing 1, where it is secured by means of a lock-nut 16. The rear end of said member has a flange 17, which is tightly seated in a recess 18, provided for its reception in the open end of the easing, which in turn connected with the water main 19. The inner valve member or spigot 13 consists of a conical shell fitted in the outer member or seat 12, and having a stem 20 at its small end,which projects through the tubular stem 1%, which is provided with a stuffing-nut 21 to make a tight joint. The seat 12 and spigot 13 have ports 22 23,wh1ch are adapted to register with each other, and which may be opened or closed by a quarterturn. These ports are triangular in shape, as will be seen in Figs. 6 and 7. By this construction the portsnrhen opened ,will admit the water rapidly, while in shutting off the water will be shut off gradually, thereby avoiding The stand- )1 )e which extends u in the seat, which communicates with the stand-pipe. The channel 24, it will be seen, thus serves as a drain for the latter and effectually prevents water from remaining and stagnating or freezing therein.

The valve stem is provided with a weighted lever 25, to which isconnected a rod 26, and a rod 27 is connected with the'upper end of rod 26. A similar rod 27 is connected to the hand-lever 7, which is pivoted to the drop-pipe 4, and the ends of the rods 27 27 are connected by a chain 28, passing over sheaves 29, journaled to the inner side of one of the upright arms 8. It will thus be seen thatwhen the drop-pipe is lowered and within reach the valve may be readily opened by operating the hand-lever 7, the weighted lever serving to close it automatically when the hand-lever is released.

For the purpose of relieving the force with which the spigot or valve member 13 is held to its seat by the pressure of the water in the main and the difficulty in turning the valve resulting therefrom, I avail myself of mechanism as follows: Upon the outer ends of a series of bolts 30 30, extending laterally from the valve-casing parallel to and around the stem of the valve, I secure a block or plate 31, having a short cylindrical bore 32 concentric with the valve-stem, and in which is fitted a piston 33, having a stem 34, the inner end of which bears against the valve-stem, and is provided with an angular channel 35, registering with the channel 24 in the latter. Upon the bolts 30 at the outer end of the cylinder 31 is secured a head 36,11aving in its inner side a recess 37 and provided with an opening 38, v

which is connected by a small pipe 39 with the Water-main 19. It follows that the water from the latter will enter the recess 37 and the bore 32 in the cylinder and force the piston 33 in the direction of and against the valve-stem with a force equal to that exercised by the water against the inner or rear side of the valve member or piston 13. By properly gaging the area of the piston it will thus be seen that the valve may be balanced as nearly as may be desired, thus reducing the force required to turn it in its seat very considerably.

In a valve of the dimensions necessary for a railroad stand-pipe the water hammer or blow caused by the cumulative increase of pressure when the flow is suddenly out off is very. considerable and severely injurious both to the valve and pipes. For the purpose of reducing or doing away with the efiects there of, I connect the main with the stand-pipe by an elbow-pipe 40, in which is located a valve 41, which is normally held closed by the action of a spring 42, the pressure of which is somewhat greater than the normal pressure of the water in the main. It will be seen that when the water is cut off suddenly the eumulative energy of pressure will be exerted against the spring 42, thus opening the valve 41 and permitting water to flow through the pipe 40 into the stand-pipe. As soon as the increased pressure ceases the valve 41 is returned to its seat by the action of the spring. By this device excessive strain upon and injury to the walls of the pipes are effectually avoided. I

The operation and advantages of my invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed,by those skilled in the art to which it appertains. The construction of the stand-pipe is comparatively simple and inexpensive, and the drop-pipe connecting-pipe carrying the discharge-nozzle may be lowered to either side, while the union-elbow which forms the discharge-nozzle may be turned so as to discharge the water downwardly on either side. The standpipe may therefore be arranged between two railroad-tracks and used for supplying water to engines on either track.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1. In a stand-pipe, the combination of a lower rigid pipe-section, a rigid drop-pipe having a swiveled or union elbow, a flexible connectingpipe, and pivoted connectingarms attached rigidly to the lower section and to the drop-pipe,respectively, substantially as set forth.
